Just make sure that power is reaching the innards of the set. Does not appear so.

Hello!
most probably the fuse inside the circuit blown out, You should open the back of the tv to become circuit board visible. But this hard when novice do it.
To be sure that everything will be alright i would rather suggest you to bring the tv to the nearest service center. maybe warranty work for that.
best regards,melnavz

hi first call you cable company and let them that your cable box cought firer then call samsung cause you have a year if anything happens just know that you may have to pay for repairs

Sorry, but welcome to the world of highly efficient, component-critical switching power supplies.
These are all of those things and the failure often is related to a specific type of component, an electrolytic capacitor.
These are chemical devices and cheap ones fail easily, the most expensive take little longer but the primary value shrinks while the losses climb until the part cannot do what it should any more.
The main power supply is probably at
fault and without some technical background and a couple of test instruments,
you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it
stand overnight or at least several hours, remove the back panel and look for a
separate board with mostly larger components on it; it will have a ferrite core
(no laminations as with a line-frequency part) transformer on it and several
larger capacitors which are cylindrical and mounted vertically to the board.
Before touching anything inside, especially on
that board, allow several hours to be safe since the larger capacitors can hold
a painful voltage charge for some hours.
If you see signs of overheating such as
discoloration of the board material, it may not be repairable but if you can
find a part number on the board, you might be able to buy the power supply and
install it yourself but it will likely have the same problem eventually unless
they have altered the design.
If there are no signs of heat damage to the board,
there may be companies offering to repair it as a subassembly instead of
repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the
power supply still may not be at fault since most are capable
of switching on and off if a downstream problem is causing an overload.

Check the fuse on the power board also check and replace any swollen capacitors on the power board. If still no power then replace the power board.

for your convenience, the manual may be downloaded from here: http://tv.manualsonline.com/manuals/mfg/samsung/un40c5000.html
it should be included somewhere within the 104 pages of the pdf.
